Stage iii-b colon cancer removed surgically. Suspected liver lesion resected and analyzed with not malignancy. Is kras analysis needed for recurrence?
Possibly: For initial treatment after surgery, you shouldn't need to get kras testing. However, if this is metastatic or recurrent colon cancer, then it may help to determine if egfr based therapies like Cetuximab can help (they only work for kras "wild type"). Remember that if you do recur (god forbid), management may be different at that future time! not something to worry about with your current story. ...Read moreSee 1 more doctor answer
Surgical resection: Colonic carcinomas cause problems because they arise in lumen of the bowel and as they grow tend to obstruct, and in distal colon, where fecal material is solidified, bleeding will occur. This all in advance of metastasis which is also why early resection important. In older patients with large mass radiation and chemotherapy can be given. Obstructed distal lesions can betreated with stent. ...Read more

Screening with colonoscopy started at age of 50. ...Read moreSee 2 more doctor answers
Cancers: Cancers are abnormal, rapidly growing cells that do not know when to stop growing. These abnormal cells can damage local tissues, can attach to nearby organs or structures, can spread to lymph nodes, or can spread to other organs through the blood stream. Their growth damages what they are attached to, and often cancers encourage new blood flow to themselves. Cancer can grow in the colon. ...Read moreSee 1 more doctor answer
Not always: Colon cancer tends to not have any signs or symptoms when it is early (when it is easiest to treat). That is why screening colonoscopies are so important, to remove any polyps that may become cancer, and to directly look for cancers. Colon cancer can cause bleeding from the rectum, tiredness from anemia, stool changes, or abdominal pain. Other things can cause this too. Best to be seen if ?S. ...Read moreSee 1 more doctor answer
Usually not: Early stages of colon cancer often have no symptoms. Colon cancer has long developmental stages starting out as polyps and can take yrs to develop, hence screening colonoscopy is done every 10 yrs for normal folks. Polyps can be removed during colonoscopy. Advanced cancer can cause pain by obstructing bowel, spread to liver, bone, brain, lung etc. See doc regulalry.
